  • Silicone hydrogel contact lenses and related compositions and methods
    Patent number: 8513325
    Abstract: Silicone hydrogel contact lenses are produced without using volatile organic solvents to extract materials from the polymerized contact lens bodies, and instead are washed with aqueous liquids. The silicone hydrogel contact lenses so produced have ophthalmically wettable lens surfaces. The hydrated silicone hydrogel contact lenses have diameters that are at least 24% larger than the diameters of the silicone hydrogel contact lenses prior to hydration or washing.

  • Multifocal Contact Lenses And Related Methods And Uses To Improve Vision Of Presbyopic Subjects
    Publication number: 20130201443
    Abstract: Multifocal contact lenses and methods and uses are described. The multifocal contact lenses include an optic zone. The optic zone has an aspheric power profile that provides a near vision refractive power and a distance vision refractive power, and provides an Add power that corresponds to the difference between the near vision refractive power and the distance vision refractive power. The multifocal contact lenses can improve binocular vision of presbyopic subjects by being prescribed such that the non-dominant eye contact lens is over-corrected for distance vision, and both multifocal contact lenses are under-corrected for the Add power requirement of the subject. Batches and sets of multifocal contact lenses are also described.
